SPRING-HINGE.

Specification of Letters Patent.

Patented Nov. 27, 1906.

Application filed September 30,1902- Serial No. 226.659.

To all whom it may concern.-

Be it known that we, CORNELIUS S. VAN WAGONER and LE DRU R. POMEROY,citizens of the United States, residing at Cleveland, in the county ofCuyahoga and State of Ohio, have invented new and useful Improvements inSpring-Hinges, of which the following is a specification. 3

Our invention relates to that class of double-acting spring-hinges whichare designed to be applied for pivotally supporting a door at its top orbottom edge instead of at the rear side edge; and said inventionconsists in the novel features hereinafter de-I scribed, andparticularly pointed out in the claims hereunto annexed.

In the drawings furnished and forming a part of this specification,Figure 1 is an elevation of a portion of a door and door-casing,

showing our improved hinge as applied to the upper rear corner of thedoor; sectional view of the pivot, shown in Fig. l as being mounted forsupporting the lower edge of the door. proved hinge with the detachableportion of the casing removed and a portion of the main frame brokenaway. Fig. 4 is a verti cal section of said hinge on line 44 of Fig. 3.

Fig. 5 is a horizontal sectional view on line 5 5 of Fig. 3. Fig. 6 is ahorizontal sectional View on line 6 6 of Fig. 3. Figs. 7 and 8 arehorizontal sections, respectively, on lines 7 7 and 8 8 of Fig. 3. Figs.9 and 10 are views corresponding to Figs. 7 and 8, showing the positionsof the parts when the hinge-frame or door is turned to the right; andFigs. 11 and 12 are similar views showing the positions of the partswhen the hinge-frame or door is turned to the left.

Modern building construction has rendered it practically impossible insome instances to mount a pivot-hinge in'the door-sill or in the floordirectly beneath the bottom edge of the door, and for this reason ourhinge is designed to be attached either to the lower or the upper rearcorner of a door, as may bepreferred ,but it will be apparent thatcertain features of our invention may be applied to a hinge designed tobe mounted in the floor or door-sill.

The hinge illustrated in the drawings is shown in Fig. 1 as beingmounted at the the hub, as clearly shown in Fig. 2.

Fig. 2 1s a Fig. 3 is a side view of our imupper rear corner of a doorA, the latter being pivotally connected to the door-casing B by thehinge-spindle C, which enters a socket d, formed in a plate D, which issecured to the door-casing, as clearly shown.

The bottom edge of the door rests upon a pivot or stud E, which isadjustably mounted in a plate 6, the latter being secured in the flooror door-sill B so that the stud E will be in axial alinement with thespindle C of the hinge. The plate 6 is provided with a hub. or sleeve 6,in which the stud E is mounted, said stud being externallyscrew-threaded to receive a nut 6 which is seated in the upper end ofthe hub e for supporting the stud in In the bottom edge of the door A isa socket f, formed in a plate F, and in said socket is a ball-bearingcone f, which is held in the socket by a wire ring f seated in a grooveformed in and around the interior wall of the socket adjacent tothelower edge of the cone.

Between the cone f and thewalls of the socket is a series ofantifriction-balls f, the whole affording an antifriction-bearing forthe stud E, said stud being reduced in size at its upper end toenter-the central opening in the ring or cone f and to afford a shoulderf upon which the cone rests for supporting the door. The said stud E israised and lowered for securing the door in or removing it from itscasing by turning the nut e*, the stud being held against rotation by apin e secured to the hub e and projecting into a groove or slot 6 in thestud, as will be readily understood.

As shown in Figs. 1 and 3 of the drawings, the main frame G of the hingeis shaped to fit a substantially rectangular mortise cut in the cornerof the door, said frame forming three sides of a casing or inclos'ure inwhich the working parts of the hinge are housed and being provided withextensions or straps g and g for securing it to the door by means ofscrews g as clearly shown in Fig. 1. The spindle'C is mounted in theparts g and g of the main frame, which form the top and bottom or thetwo end plates of the hinge-casing. Said spindle projects through thepart 9 and is provided with a non-circular head 0, which enters asimilar-shaped socket d in the plate D, already referred to, saidspindle being held by said plate against rotation, as will be readilyunderstood. Both of the spindle-bear ings are provided withball-bearings. The lower bearing consists of a hard-metal ring or conemounted on antifriction-balls 0 which are confined in a hard-metal. cup0 the latter being inserted in a depression formed in the part g of themain frame. The spindle has a reduced end 0, which enters the ring orcone 0, the shoulder bearing upon the cone, as clearly shown in Fig. 4.At the opposite end of the spindle there is a hard- .metal ring or cone0, which tightly fits the spindle and which bears upon or againstantifriction-balls 0 held in a hard-metal cup or raceway 0 mounted inthe part g of the main frame. These bearings are such as to adapt thehinge for use either at the upper or the lower rear corner of a door, asmay be preferred.

The hinge-controlling spring H surrounds the spindle and has one end-secured to a disk I, mounted on the spindle and provided with a pair ofstops or projections 71 i, located on opposite sides of the spindle,which bear against the opposite ends of a pin 0 driven through a hole inthe spindle and projecting laterally from opposite sides thereof. Thestops i i on the disk I also bear against stops 70 k, which project froma disk is, forming one end of a yoke K, which is pivotally mounted onthe spindle C.

The opposite end of the spring is secured to a tension-regulating diskL, which surrounds the spindle and also surroundsa hub m of a disk M,the two disks being adjusted with reference to each other for regulatingthe tension of the spring by means of the holes Z in the disk L, thehole m in the hub of the disk M, .and theconnecting-pin Z, as will bereadily understood. The disk M. is provided with a pair of stops m whichbear on opposite ends of a pin 0 projecting laterally from oppositesides of the spindle C. Said stops m also bear against stops k on a disk763, which forms the other end of the yoke K. The stops m m on the diskM and the stops i i on the disk I are arranged to bear in opposite 5directions on the spindle through the pins 0 and 0 and-also on the stops7c 7s and k k on the disks k and k to cause the spring H to be wound atone end when the main frame is moved in one direction and to be wound atthe opposite end when said frame is moved in the other direction, theoppositeend of the spring in each case being held stationary by thespindle C.

It will be noted that the yoke K is pivot- .ally mounted on the spindleC by reason of .the fact that said spindle passes through the disk 7cand k which form the ends of the yoke. These disks are connectedtogether to .form .a yoke in order that the stops carried with respectto the main frame. These stops are acted upon by the spring H to returnthe main frame to a central position whenever said frame has been moved.in either direction, and in order that this central position maycoincide with the position the door should occupy when closed it isoften necessary to adjust said stops so that the door when in itsposition of rest will occupy the desired position. The adjustment iseffected by moving the yoke'K. The latter, as shown in Fig. 5, projectsinto a slot n in the main frame, said slot being of a width suflicientto provide for the necessary movement. The main frame is provided withtwo screws N N, which bear on opposite sides of the yoke to formadjustable locking-abutments. It will be readily seen that bywithdrawing one of said screws and advancing the other the position ofthe yoke may be changed for varying the location of the stops carriedthereby.

For the purpose of clearly illustrating the operation of the hinge wehave-illustrated in Figs. 7 to 12, inclusive, the positions of thestops, first, when the hinge is in its normal position of rest; second,when it has been moved to the right, and, third, when it has been movedto the left. Figs. 7, 9, and 11 are sectional views on line 7 7 of Fig.3, and Figs. 8, 10, and 12 are similar views taken on line 8 8 of Fig.3.

The stops k 70 at the lower end of the yoke K, Figs. 7, 9, and 11, andthe stops 7c 7c at the upper end of said yoke, Figs. 8,10, and 12, movewith the main frame. The spindle C is held stationary by its engagementwith the socket d in the door-frame. The stops m m being connected tothe lower end of the spring H, bear (when the hin e is in its normalposition of rest) direct y against the stops k k and also-against thepin 0 carried by the spindle, as shown in Fi 7, while the stops i i,which are connecte to the other end of the spring, bear against thestops 7c 7c and also against the pin a of the spindle C. When the mainframe is moved to the right, the spring is wound at the bottom bypressure of the stops k k on the stops m m as shown in Fig. 9, the otherend of the spring being held stationary by the pin 0 which is inengagement with the stops & 'i, as shown in Fi 10. th? left, as shown inFigs. 11 and 12, the

lower end of the spring is held stationary by When the main frame ismoved to IIO the engagementof stops m m with the pin 0 the other end ofthe spring being wound by pressure of the stops 7c 74 on the stops '1'i, the spring operating to return the door to its closed positionregardless of the direction in which it has been moved, as will bereadily understood. The working parts of the hinge are completely housedby means of the thin sheet-metal plates P P, which are secured tothereby may be simultaneously adjustedfi the .main frame by means of thescrews p,

(shown in Fig. 1,) and it will be seen that by removing said plates allparts of the hinge are accessible for adjustment and repairs with outremoving the hinge from the door to which it is attached.

Should it become necessary to replace the spring or any other part ofthe hinge, this may be done by removing the pins 0 and 0 from thespindle C. The parts of the hinge may then be separated without removingthe main frame from the door.

Having thus described our invention, what we claim as new, and desire tosecure by Let ters Patent, is

1. In a spring-hinge of the character described, a main frame, a spindlemounted therein having a pair of projections or stops against which theopposite ends of the controlling-spring may operate, a spring mounted onsaid spindle between said stops having its opposite ends arranged tobear upon said stops in opposite directions, separate stops carried bythe main frame also arranged to be operated upon in opposite directionsby the opposite ends of said spring and means for simultaneouslyadjusting the last-mentioned stops for the purpose set forth.
